Drug delivery devices including disposable and reusable components

Abstract

The present invention provides a reusable device that facilitates the dispensing of medications and / or the replacement of used cartridges with new ones. [Solution] The therapeutic drug delivery device includes a disposable portion and a reusable portion that detachably carries the disposable portion. The reusable portion includes a drive mechanism having a guide, a rotary actuator, and a driven portion that is drivably coupled to the rotary actuator and movably coupled to the guide. The rotary actuator is actuated to drive the driven portion rotatably, the driven portion thereby following the guide and translating the drive mechanism. The drive mechanism thereby translates the syringe assembly of the disposable portion from a housing configuration to an unfolded configuration.
